Title: Semiconductor Device and Method of Making the Same
IPC: H01L27/00
Filed: 1967-03-17
Abstract: 1,175,603. Semi-conductor devices. SONY CORP. 17 March, 1967 [19 March, 1966 (2); 22 April, 1966], No. 12694/67. Heading H1K. A passivated PN junction semi-conductor device is manufactured by a method which includes depositing on the semi-conductor surface a material (e.g. lead, lead oxide, magnesium, zirconium, aluminium or beryllium) which when heated in an oxidizing atmosphere will react or combine with the semi-conductor material (e.g. silicon) to form a glass at a temperature lower than that at which the semiconductor itself would be oxidized. After deposition, heating at the requisite temperature takes place for a period sufficient for the glass which is formed to extend into the semiconductor as far as or beyond the level of the PN junction. The resulting structure may thus contain, as in Fig. 1E, a PN junction 14 completely surrounded by a glass annulus 16 located within the semi-conductor body. Alternatively, as in Fig. 1E<SP>1</SP>, the surface portions 14a of a junction may be left unprotected and the glass annulus 16 may break through the junction 14 to surround a portion of it and isolate such portion from the surface portions 14a. The deposited glass-forming substance is confined to the appropriate surface portion of the semiconductor body by the use of a mask 15 consisting of a deposited layer of a metal, such as molybdenum, tungsten or platinum, which does not react with either the semi-conductor or the deposited substance. The choice of the latter substance and of the oxidation treatment conditions is preferably such as to ensure that the mixed oxide glass formed will have substantially the same expansion coefficient as the semiconductor. Fig. 31 depicts a transistor in which both the junctions 23 and 25 are encircled by respective glass annuli 22 and 24 formed-either sequentially or simultaneously-by the method described above. Fig. 4H shows a portion of a multi-transistor structure in which the base and emitter regions 42b and 42e of adjacent transistors are isolated from each other by a glass layer 43 formed by oxidation and growth into the semi-conductor, as described above, as far as the collector junction jc. The several transistors have a common collector zone 42c. Each ingrown glass portion, which was originally of the same form as the annuli 16, 22 and 24 above referred to, has been partly etched away by the removal of redundant glass from the regions 48. Fig. 5C shows part of an integrated circuit in which glass has been formed and grown upwards from the whole of the lower surface and downwards from selected regions of the upper surface of a semi-conductor body to provide completely isolated semi-conductor regions 50. Separate devices have then been formed in each of these regions by diffusion of impurity to produce PN junctions therein. In this embodiment therefore, the glass which extends into the semi-conductor to beyond the level of the PN junctions in the completed device has been formed in the semi-conductor before the junctions themselves.

Patent GB-1283801-A (GB)
Title: Speed governor providing average phase synchronism
IPC: H02P9/04
Filed: 1970-03-17
Abstract: 1283801 Automatic speed and phase control WOODWARD GOVERNOR CO 17 March 1970 [18 March 1969] 12840/70 Heading G3R A system for controlling the speed of a prime mover forms an error signal by comparing the phase of pulses produced at a frequency proportional to the actual speed of the prime mover which the phase of reference pulses derived from an oscillator. The error, which may represent a phase difference greater than 360 degrees, is used to adjust the input to the prime mover to maintain a predetermined phase relationship. In the embodiment shown in Fig. 1, pulses indicative of the speed of prime mover 10 are produced by a transducer 20 comprising a toothed wheel 21 co-operating with a magnetic core 22 and pickup coil 23. These pulses are fed to a conventional speed control circuit 30 including a shaper 31, integrator 33 and comparator 40 in which a voltage representing the actual prime mover speed is added at a junction 43 to a reference voltage derived from a D.C. source 51. The resulting signal is fed to a fluid-pressure actuator 70, Fig. 2 (not shown), which controls a throttle 12 on the primer mover. At the same time, pulses from the transducer 20 are also supplied to a phase control network 110. The other input to this network is obtained from an oscillator 120, and both trains of pulses are fed through dividers 131, 132 which produce one output pulse for every 16 input pulses. A flip-flop circuit 140 serves as a phase comparator for these output pulses, and in turn produces a square wave output at terminal 146. This output is integrated by RC circuits 150 to produce a phase error signal at terminal 113 which is zero if the divided phase input signals are 180 degrees out of phase. A phase difference of 360 degrees causes rollover, indicated by a circuit 195, 196, but this occurs infrequently due to the presence of dividers 131, 132, since it is the output pulses from these circuits, rather than the input pulses, which have to reach the 360 degrees phase difference. The phase error signal is fed to the summing junction 43 so that, after a sudden change of load, the prime mover speed will be deliberately overcorrected for a time until the original phase relationship is restored. If desired, the speed control circuit 30 may be omitted, and phase control only may be relied upon to maintain the speed constant, but such a system would have a longer response time than the arrangement described above. Changes in desired speed may be effected by a control 197 which simultaneously adjusts the frequency of oscillator 120 and the speed reference level provided by source 51. In a second embodiment, Fig. 7 (not shown), a single phase control network is used to maintain the phase relation of four prime movers, each with its own speed control circuit, driving alternators which feed common power lines. In this case, the actual phase signal is taken direct from the power lines.

Title: Improvements in cloth and like guiders or feeders
IPC: D06C3/00
Filed: 1921-05-05
Abstract: 184,256. Wood, A., and Wood, G. May 5, 1921. Feeding webs.-Relates to devices for guiding a cloth web into calendering, stentering, or other finishing - machines, of the kind in which pairs or sets of rollers engaging the selvedges and arranged at an angle to each other are operated to grip or release the cloth by magnetic, pneumatic, or mechanical devices controlled by feeler levers engaging the edges of the web, and consists chiefly in making one roller of each pair or set shorter than the rem.aining roller or rollers, and adjustable bodily in an axial direction to suit fabrics of different width, in arranging the magnetic &c. operating devices at points removed from the rollers, and in arranging the feeler-lever carriers to be adjustable independently of the rollers and parallel thereto. As shown, a pair of rollers is arranged at each side of the cloth and comprises long rollers d<1> and short rollers e carried by arms k' of sleeves k adjustable along bars l parallel to the rollers d<1>. The bars l are rotatable in their bearings m, o to move the rollers e into and out of contact with the rollers d<1>, and carry the armatures p of electromagnets q mounted on the side frames a of the machine. The electromagnets are carried by a plate adjustable in a housing r by a bolt r<3> and slot r<1>. Each feeler carrier t is adjustable on a bar s parallel to the roller d<1> and comprises a box member v, Figs. 4 and 5, with side plates w between which the cloth passes. The feeler-lever x pivoted in the box v has a pin x<4> bridging the plates w and working in slots w<1> therein, and has a pin x<5> operatically engaging a spring switch contact x<3> co-operating with an adjustable contact x<1>. When the cloth deviates from its true path the lever x is turned and closes the contacts x<3>, x<1>, thereby closing the circuit of a relay magnet which then acts to break the circuit of the magnet q, allowing the roller e tn move, clear of the roller d<1> until the other pair of rollers restores the web to its correct path. The contacts x<3>, x<1> may normally touch the breaking of the relay magnet circuit causing the breakage of the main magnet circuit, and the rollers e, d' may be normally separated, being brought into engagement only when the cloth is not running true. Instead of the magnet q, pneumatic devices may be provided and controlled by the feeler-levers magnetically or mechanically such as by a Bowden wire.
